Probing conformational states of glutaryl-CoA dehydrogenase by fragment screening
Glutaric acidemia type 1 is an inherited metabolic disorder which can cause macrocephaly, muscular rigidity, spastic paralysis and other progressive movement disorders in humans. The defects in glutaryl-CoA dehydrogenase (GCDH) associated with this disease are thought to increase holoenzyme instability and reduce cofactor binding. Here, the first structural analysis of a GCDH enzyme in the abse...
متن کاملTeaching NeuroImages: Glutaric aciduria type 1 (glutaryl-CoA dehydrogenase deficiency).
A 14-month-old boy presented with loss of developmental milestones and tonic spasms following a diarrheal illness. He was born to nonconsanguineous parents and had mild motor delays. Examination was remarkable for macrocephaly, axial hypotonia, and asymmetric dystonic posturing of neck, trunk, and extremities. Brain MRI (figure) and elevated glutaryl carnitine on tandem mass spectroscopy were d...
متن کاملDisease-causing missense mutations affect enzymatic activity, stability and oligomerization of glutaryl-CoA dehydrogenase (GCDH).
Glutaric aciduria type 1 (GA1) is an autosomal recessive neurometabolic disorder caused by mutations in the glutaryl-CoA dehydrogenase gene (GCDH), leading to an accumulation and high excretion of glutaric acid and 3-hydroxyglutaric acid. Considerable variation in severity of the clinical phenotype is observed with no correlation to the genotype. We report here for the first time on expression ...
متن کاملMultimodal imaging of striatal degeneration in Amish patients with glutaryl-CoA dehydrogenase deficiency.
Despite early diagnosis, one-third of Amish infants with glutaryl-CoA dehydrogenase deficiency (GA1) develop striatal lesions that leave them permanently disabled. To better understand mechanisms of striatal degeneration, we retrospectively studied imaging results from 25 Amish GA1 patients homozygous for 1296C>T mutations in GCDH. Asymptomatic infants had reduced glucose tracer uptake and incr...
متن کاملInteraction of Glutaric Aciduria Type 1-Related glutaryl-CoA Dehydrogenase with Mitochondrial Matrix Proteins
Glutaric aciduria type 1 (GA1) is an inherited neurometabolic disorder caused by mutations in the GCDH gene encoding glutaryl-CoA dehydrogenase (GCDH), which forms homo- and heteromeric complexes in the mitochondrial matrix. GA1 patients are prone to the development of encephalopathic crises which lead to an irreversible disabling dystonic movement disorder. The clinical and biochemical manifes...
